Abstract
A controller for a multi-level converter compares a first voltage proportional to an input voltage or an output voltage with a second voltage proportional to a voltage of a flying capacitor and adjusting a slope of a ramp signal for generating a pulse width modulation (PWM) signal so that the second voltage follows the first voltage in controlling the multi-level converter.
